以皱纹盘鲍鱼壳为对象,研究了其结构与力学性能之间的关系.研究表明,鲍鱼壳主要由方解石和文石构成,且外层为方解石,内层为文石.鲍鱼壳的力学性能随其加热温度的升高而明显降低,密度也呈现同样的变化,说明鲍鱼壳中所含有的少量有机质随着加热温度的升高而减少,致使鲍鱼的力学性能明显下降.
The relationship between the structure characteristics and mechanical properties of the Haliotis discus hannai ino shell is investigated. It is indicated that the shell is composed of calcite and aragonite. The out layer is composed of calcite,while the inner layer is composed of aragonite. The mechanical properties of the shell decrease significantly with increasing temperature,and its densities show the same trend. It can be concluded that the small amount of organic matter decreases with increasing temperature and it leads to that the mechanical properties of the shell decrease significantly.
